Gravity has a different value at every point in space. Time flows differently at every point in space. The value we learn of gravity in class is an average for Earth. A second is the average length of time so much radioactive material decays to another state on Earth or the average time it takes for the mechanism of a second hand in a watch or a digital clock etc. to say a second has passed. Time is a continuum, it is a force. Better said, time does not really exist, it is just a human designation of one aspect of the Unified Force which behaves like a dimension within which interactions can take place. The interactions between forces create "time" which is really just another aspect or field within which forces interact. Time is a subjective, though useful concept. Many theorems now can be stipulated without using the concept of time.
